ALCOHOL LAMP.

Application 'inea March 151, 192e. sefiai no. Meer.

' 5 vices of this description' which may be utilized for variouspurposes, especially forincubators, brooders andthe like.v

lith these ends in view,- this invention consists in the details ofconstructiongand 10 combination lof elements hereinafter set forthv andthen specifically designa-ted by the claim. In order that those skilledinthe art to which this invention apperta-ins, may understand how tomake and use the same, I will describe' its construction in" detail,referring by numerals to the accompanying drawings forming a part ofthis application, in which Fig. 1, is a plan View of my improved alcohollamp.

Fig. 2, is a side elevation of Fig. 1, partially broken away andsectioned to show the interior construction of the lamp and alsoillustrating a portion of an incubator as an example of an applicationofthe device.

In carrying out my invention as here embodied, 10 represents a tank oralcohol supply reservoir having a collar 11 projecting upwardlytherefrom, over which the tubular base 12 of the lamp is adapted tosnugly fit to prevent the escape of liquid or fumes at this point.v 13represents a tubular shank formed with the body of the lamp 14, thisshank extending intov the base and being secured thereto, either byfriction or in any other suitable manner. TheV body 14 is ofconsiderably larger diameter than the shank 13, and has onefor moreseries of holes 15 formed around the upper portion thereof, and aroundthis body is fitted the sleeve 16 adapted to loosely slide up and downupon the body so as to regulate or direct the How of vapor from theholes 15,V as hereinafter explained.

17 represents a bail, the ends of which are pivoted to the sleeve 16 bymeans of the studs 18, and this bail carries a stem 19, adapted to beattached to a lever 20 connected with the usual thermostat of anincubator 31 or the like.

21 represents a cap adapted to fit snugly over the upper end of the body14, and this cap has projecting upward therefrom a prong 22; the cap andprong preferably bematerial.

ing of copper orvother high heat conducting 23" represents a pilot cupwhich is provided with a shank 24 adapted to fit up'on theV shank 13' ofthe body and be held in place by friction o'r otherwise, and this cup asillustrated in the drawing is intendedy to be positioned just below thelower portion of the body and spaced therefrom sufiic'iently to" perm'itthe insertion within the cup ofa suitable absorbent'material 25.'v

26 representsa fibrous wick which extend thru the' shank 13y andbelowthe samesufiiciently to' reach into and preferably to the bottom ofthereservoir 10, the' upper end ofv the wick beingmore lorpless expanded soas to approxiniately vfill the lower'y portion of th-e body 14 in orderthatalcoho'l may be drawn by capillary attraction from the-reservoirthru the shank 13 and .expanded to vaporization at the 'upper end of thewick.l

From the foregoing description the operation of my improved alcohol'lampwill be obviously as follows: The reservoir 10 is supplied with asuflicient quantity of alcohol by filling it thru a suitable inlet 27and the wick will absorb and raise a supply of alcohol within the lowerportion of the lamp, where it will be vaporized by the heat generatedfrom the pilot cup 23 which has been previously saturated with alcoholor'other easily ignited material and lit.

The vapor thus generated within the body of the lamp will bel forcedthru .the openings 15 andv ignited by the fiameissuing from the pilotcup so that thereafter these jets of flame will continue tov burn vafterthe pilot light has been exhausted.

The jets of vflame issuing from the openings 1,5 will continue to heatthe body, its cap and prong 22 and thus continue'to generate the vapor.for supporting said jets of flame; the prong being extended to absorbthe heat ofthe jets of flame, and thus insure the proper temperature ofthe body to continue the generation of the proper amount of vapor.

When the device is applied to an incubator Vor the like, and the stem19y connected with with the leverv 2() of the usual thermostat mountedin such apparatus, the lowering of f the temperature within theapparatus below the heating capacity of the lamp increases the responseof the thermostat to this heat increase will cause the sleeve 16 to belowered and thus permit the flame jets to project away from the body 14Cand thereby again lower the temperature.

lVhile I have shown and described the sleeve 16 as being' operated by athermostat, it is to be understood that an equivalent manually operablemechanism may be substituted tor said thermostat. It has been 'found inpractice that a lamp made in accordance with my improvement may be solinely adjusted that the temperature Within the incubator or likeapparatus will beso controlled asrto maintain a temperature almost treefrom fluctuation, the variance beingonlyxa traction of a degree ofFahrenheit.-

One otthe advantageslof my improved lampfis that vitis lightei.' otconstruction, easily assembled, and'is readily dismembered for cleaningor repairing. 1

Of course I do not Wish to be limited .to the exact detailsbfconstruction as herein shown as these may be varied Within the limitsot' the Vappended claim WithoutV departing from the spirit oit' myinvention.
